STREET-BOX FOR GAS OR WAT'ER PIPES.

SPECIFICATION forming part of Letters Iatent No. 530,581, dated December11,1 894.

Application filed March 23, 1894. Serial No. 504,785. (No model.)

dianapolis, in the county of Marion and State of Indiana, have inventedcertain new and useful Improvements in Street-Boxes for Gas andWaterPipes, of which the following is a specification.

1 The object of my said invention is to provide the ordinary streetboxes for gas and water pipes with caps which may be securely put inplace without forming any opening through thecap through which moisturemight enter, thus subjecting the box to the disad vantageof freezing,with the attending difliculties of removing it when required,.in coldweather.

Said invention will be first fully described, and the novel featuresthereof then pointed out in the claims. a

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a perspective view of a fragment of a side-walk showing the upperend of an ordinary street of curb box; Fig. 2, an under side perspectiveview of the cap to the box; Fig. 3, an upper end perspective view of thebox when the cap is removed; Fig. 4, a central sectionalview of theupper end of the box and'cap when assembled to gether, and Fig. 5 ahorizontal sectional'view looking downwardly from the dotted line 5 5 inFig. 4. I

In said, drawings the portions marked A represent the street or curbbox, and B the cap thereto.

The upper end of the box A is provided with flangesawhich extend aroundthe greater portion of its inner circumference, as shown most plainly inFigs. 3 and 5, said flanges, however, being cut away for'a portion ontwo opposite sides. The under sides of'the flanges are tapered, as shownin Fig. 3, one in each direction.

, The cap 13 is of sufiicient diameter to completely cover the upper endof the box A, including the flanges thereon, so that no part of said boxis exposed upwardly. Said cap has a tubular central extension part Bwhich is smaller in diameter than the interior of the box A-and extendsdown, when the cap is in place,inside said box, and upon two oppositesides of this tubular portion are wings or extensions b' which areadapted to engage with 5 5 the under sides of the flanges a, In the topof the cap B is a cavity with a cross-bar b to which a wrench may beapplied in opening and closing the box. The method of using this deviceis to drop the tubular portion B of the cap B into the upper end of thebox, with the projections b so positioned as to pass down through thepoints where the flanges a are cut away, or do not extend, and then toturn the cap with a wrench until the projections I) come forciblyagainst the under sides of the flanges a, which obviously holds the captightly and firmly in place. In opening, the cap is turned backwarduntil the proj ections b arebelow the spaces between the flanges a; whenthe cap can be easily lifted out.

Havingthus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1 The combination, in a street box for gas 7 5 and water pipes,of thecylindrical box A having the interior flangesataperedl on their undersides and cut away or havingspaces between their ends, said interiorflanges being at the extreme upper end, which is continned out and formsan'annular flange projecting from the exterior surface of the boxproper; and the integrally constructed cap or cover B extending over.the whole top ofthebox A and forming a complete roof therefor, and

having acentral downwardly extending tubular projection, smaller thanthe interior of said box A, and provided with small projections or wings12' adapted to engage with the under sides of the inclined flanges a,all substantially as shown and described.

2. The combination, in a street box for gas and water pipes, of thecylindrical box A having at the upper end the interior flanges a,

said flanges being tapered on their under sides 9 5 and cut away orhaving spaces between their ends; and the integrally constructed cap orcover B extending over the whole top of the box A and forming a completeroof therefor,

and having a central downwardly extending 10o tubular projection,smaller than the interior of said box A, and provided with smallprojectibns or wings'b adapted to engage with In witness whereof I havehereunto set my the under sides of theinclined flanges a, and hand andsea], at Indianapolis, Indiana, this also provided with a centralexterior depres- 19th day of March, A.
